Non-inflammable solvent for paints and the like.



GEORGE WHIGELT, OF NEW YORK, N. Y.

NON-INFLAHMABLE SOLVENT FOB, PAINTS AND THE LIKE.

No Drawing.

To all whom it may concern:

Be it known that I, GEORGE VVHIGELT, a

citizen of the United States, and resident of' Dongan Hills, in the county of Richmond, city and State of New York, have invented a new and useful Non-Inflammable Solvent for Paints and the like, of which the following is a specification.

My invention relates to a new composi tion of matter capable of dissolving and reoving old paint and varnish and other coatings of kindred materials from wood, metal, stone and other surfaces. The new composition may also be used as an ingredient in the manufacture of paints and varnishes and allied materials to aid in the dissolving of gums, resinous materials, oils, fats, etc.

The new composition described below is of great practical value on account of its non-inflammable and non-explosive character and in View of the fact that its mixture with explosive and inflammable liquids will produce compounds retaining its non-ex-- plosive and non-inflammable, properties. Furthermore it has been found that the admixture of waxes to prevent evaporation is not necessary as the basic products are of a high boiling point and volatile only to a very slight degree or not at all, retaining thelr solvent power indefinitely.

In preparing my improved composition of matter, adapted for use as'a non-inflammable and non-explosive solvent or remover,

I may make use of the following ingredicnts: (A) Halogen (and especially chlorin) derivatives of acetylene; as examples of substances in this' ou I will name dichlorethylene (C (31 trichlorethylene (G HCl perchlorethylene (C 01 tetrachlorethane (C H Cl and pentachlorethane (C HCI (B) Halogen (and especially chlorin) derivatives of glycerin or glycol; as examples of this roup I will name monochlorhryidrin (C, ,()l (HO),), dichlorhydrin (C Cl HO) and epichlorhydrin (C,H,QC1). (C) Oils, fats, waxes, greases, neutral liquid products of the distillation of coal or of petroleum (such as benzin), turpentine substitutes, araffin oils, dead oil, and the like; these I w1ll designate by thegeneric term of oil. (D) Metallic soaps, among which I will name particularly alumina compounds such as stearate of alumina, and palmitate of alumina.

The composition must contain at least one Specification of Letters Patent.

. a halogen derivative of acetylene with an equal amount (by weight) composed of one or more substances or oils of group C. Again, I may obtain a serviceable composition by using a halogen derivative of acetylene in conjunction with an equal amount (by Weight) composed of one or more metallic soaps (group D). The composition may contain ingredients taken from three of the above groups (but always including one or more ingredients from group A), or all four groups may be utilized in making the composition.

While a 'compositionsuitable for the purposes of my invention may be obtained by using one or more halogen derivatives of acetylene (group A) and one or more halogen derivatives of glycerin or glycol (group B), without adding any ingredient from groups C or D, such a composition would be too expensive in most cases. Therefore, in practice, for the purpose of reducing the cost of the finished product, I generally replace all or part of the ingredient of grou B, with one or more ingredients of group group D, or groups C and D. The proportions I prefer to employ are 50 parts by weight consistina of one or more halogen derivaties of acetvlene (group A), and 50 parts consisting of one or more ingredients pjf 1331c or more of the other groups (B,

The use of metallic soaps and particularly alumina compounds such as stearate or palmitate of alumina (group D), facilitates the application of the composition.

Example I: 50 parts (by weight). of tetrachlorethane and 10' parts of dichlorhydrin are mixed under agitation, preferably at a temperature of say from 200 to 250 Fahrenheit, with 30 parts of dead oil and 10 parts of metallic soap, for instance palmitate of alumina. As soon as the mixture is homogeneous, it may be allowed to cool, and is then ready for use.

Example II: Same as Example I, but omit Example III: Use 50 parts of tetrachlor "ethane, parts of dichlorhydrin, 30 parts ofbenzin, and parts of metallic soap, and

- tures containing it and explosive or inflam mable constituentssuch as benzin. Its use proceed as in Example I.

Example IV: Use .50 parts tetrachlorethane, 30 parts of dead oil, and artsof metallic soap (a1umina compoun 5 preferred) and proceed as in Example I.

My improved composition'of matter is not only itself. non-inflammable and non-explo sive, but imparts these properties to mixis therefore.perfectlysafe. It is an eflicient [purpose of preventing evaporation. 'Thecomposition is aheavy liquid, generallyj ofa ligh 'yellowish I solvent for paint, varnish and the like, and maytherefore be used to'remove paint etc. fromvwalls or other surfaces. It may also,

.as stated here'inbefore', be used as, an m'gredient in the'manufacture of paints and the like, to assist in the dissolving of gums,

resinous material's, oils, fats, etc. The c.0mposition is notvolatileat all, or only to a very slight degree, and will therefore preserve its solventpowe'r indefinitely. While I may use waxes as ingredients" ofmy com- 7 position, their addition would not be forthe cast. 'Iclaim: F 1. The herein matter, containing a'hal0g en.
